Britain’s long-running social care crisis is moving to the centre of the political stage as Prime Minister Andy Burnham prepares to put an ambitious new vision before voters: a national care service for England, free at the point of use.

Burnham argues that the country’s existing system has become too fragile to meet the demands placed upon it. In an interview with Laura Kuenssberg, he warned that a failing social care system could ultimately place even greater pressure on the National Health Service, saying that “broken social care will in the end break the NHS.”

His proposal would represent a major shift in how care is organised and funded in England. Rather than leaving families to navigate a fragmented system with significant costs, Burnham wants care to be built around a national framework, drawing comparisons with the principles underpinning the NHS.

The political stakes are already becoming clear. Burnham has said the plan will be placed before voters at the next general election, turning social care into a defining issue for Labour as it prepares for its first party conference under his premiership.

But the promise comes with a difficult question: who will pay for it?

Conservative shadow home secretary Chris Philp has challenged Labour over the potential cost, warning that higher taxes could be required to finance the proposed service. He said the Conservatives would instead seek to fund additional spending through reductions elsewhere in government expenditure.

The argument exposes one of the biggest challenges facing Burnham’s proposal. Transforming social care would require not only political backing but also decisions about funding, eligibility, staffing and the relationship between national and local government.

Burnham is also expected to unveil measures aimed at helping first-time buyers onto the housing ladder as Labour gathers in Liverpool.

For now, however, social care is emerging as the bigger test of his political agenda. After decades of debate and repeated attempts at reform, Burnham is offering voters a clear proposition: a national care system that treats support in later life as a public service rather than a financial burden increasingly falling on individual families.

Whether that vision can be translated into a workable and affordable system will become one of the central questions surrounding the next election.
